METHOD OF UNITING SHOE -SOLES TO UPPERS.

SPECIFICATION forming part of Letters Patent No.354,051, dated December7, 1886.

Application filed November 14, 1885.

T aZZ whom it may concern:

Be it known that we, ANDREW EPPLER, Jr., and ADAM E. COLE, of Boston, inthe county of Suffolk and State of Massachusetts, have invented certainnew and useful Improvements in the Method of Applying Sole Fastenings,of which the following is a specification.

Ourinvention relates to an improved method of inserting boot and shoefastenings; and it consists in employing, in connection with atubular-shaped nail having its lower end V- shaped to form parallelspurs, a horn or support placed beneath the point at which said nail isdriven, and a driver having a projection adapted to enter said tubularnail, and a driving-shoulder, as hereinafter set forth.

It has been found that in some cases the absence of a head orenlargement makes it possible for the parts united by the nail to besepa- :0 rated more easily than is desirable. To overcome thisobjectiomwe use in carrying out our method a tool the driving end orsurface of which is provided with a bearing-should er and a centralprotuberance adapted to partially 2 5 enter the upper end of the metaltube composing the body of the nail and upset the same so as to form ahead or enlargement. The bearing-shoulder insures the nail beingpositively forced through the leather, so that 0 its lower end forciblycontacting against the horn will result in horizontally spreading thespurs forming the \l-shaped end.

Of the accompanying drawings, forming a part of this specification,Figures 1 and 2 represent side views of the nail before it is driven;and 3 represents a sectional View of the Serial No. 182,789. (No model.)

nail as driven, showing also the driver and the clinching-horn.

In the drawings, a represents the nail, which is composed of a metallictube, 2, and may 0 contain a fibrous core, 3. One end of the nail isbeveled at opposite sides to form a point. The metal thus removed fromthe sides of the nails converts the end of the tube into two separateprongs or spurs, 4 at, which are spread by contact with the horn whenthe nail is driven, as shown in Fig. 3. The opposite end of the nail isentered and spread by the central protuberance, b, of the driver b, theshoulder b", surrounding said protuberance, acting at the same time todrive the nail. The nail is thus enabled to firmly hold the parts unitedby it, as will be readily seen.

\Ve claim The method herein described of applying tubular fastenings ornails to boots and shoes,

the same consisting in taking a metallic tube and beveling one endthereof on opposite sides so as to form opposing spurs 4 4, and thenforcing the said metallic tube into the leather so as to simultaneouslyspread the spurs and upset the other end, the latter forming an annularflanged head, substantially as set forth.

In testimony whereof we have signed our names to this specification, inthe presence of two subscribing witnesses, this 31st day of October,1885.
